1. A system, comprising an array of chip modules (CMs), wherein the array includes:
- a first CM; and
a second CM coupled to the first CM, wherein the first CM and the second CM each include a semiconductor die that is configured to communicate data signals using capacitively coupled proximity communication and optical proximity communication using proximity connectors, wherein the proximity connectors are proximate to a surface of each semiconductor die, wherein each semiconductor die includes an optical signal path configured to communicate on-chip signals;
wherein at least one of the semiconductor chips is configured to communicate control and data signals separately in a corresponding one of the optical signal path and an electrical signal path coupled to the capacitively coupled proximity connectors;
wherein the first CM and the second CM communicate data signals with each other using capacitively coupled proximity communication and optical proximity communication using the proximity connectors.

Abstract
Embodiments of a system are described. This system includes an array of single-chip modules (CMs), which includes a first CM and a second CM which are coupled to each other. A given CM, which can be either the first CM or the second CM, includes a semiconductor die that is configured to communicate data signals with other CMs by capacitively coupled proximity communication and optical proximity communication using proximity connectors. These proximity connectors are proximate to a surface of the semiconductor die, and the semiconductor die includes an optical signal path configured to communicate on-chip optical signals.
